Ben, I shot one deer with the 85 BTHP in 2000. He was in an open pasture so was in sight the whole time. He ran about 50 yards and stopped for a few seconds then fell over. Massive lung damage but no exit or even marks on the opposite rib cage. There was no blood trail either.
Do you get exits? I use them for coyotes and they work great for that. Very accurate.
